“Modeling of ablative material for hypersonic atmospheric entry flows, and more”
By: Dr. Alexandre Martin
Professor of Mechanical Engineering, University of Kentucky
ABSTRACT: For extra-orbital missions, ablative materials have always been, and still remain, the primary choice for the design of atmospheric entry heat shields. Because of the many uncertainties associated with the usage of such material in complex aerothermal flow environments, it is important to understand and quantify the effects of the phenomena at play. Many specific area of research can lead to a better understanding of the underlying physics of aerothermodymamic ablation. More specifically, the topics discussed will touch upon the various aspects of atmosphere entry modeling, the coupling of material response and CFD codes using a unified method, small capsule flight campaigns and a very exciting tangential applications!
BIO: Alexandre Martin is a Professor of mechanical engineering at the University of Kentucky, starting in 2010. He obtained a B.Sc. in Physics in 1998 from the University of Montréal (Québec, Canada), and a M.Sc.A. and Ph.D. from the Department of Mechanical Engineering at École Polytechnique de Montréal (Québec, Canada). He worked primarily on plasma ablation, with an application on industrial high-voltage circuit-breakers. After continuing this work as a Research Associate at École Polytechnique for a year, he then moved to the University of Michigan (Ann Arbor, MI), where he worked on the material response of atmospheric re-entry vehicles.
